What this scam is

On buy-and-sell platforms, scammers pose as eager buyers or too-good sellers. Common tricks include asking for a 'verification code' (really a hijack of your phone number), overpaying with a fake check, or pushing payment outside the platform.

What it usually looks like

  • A buyer asks for a code they 'sent' you to prove you are real.
  • A seller has a great deal but wants a deposit before you can see the item.
  • Someone insists on paying or being paid off the platform.

Common warning signs

  • A 'verification code' request is a trick to take over your account or number.
  • Deposits or payments requested before meeting or shipping.
  • Pressure to move to text, Zelle, or another app.

Example wording scammers use

I'll send a code to make sure you're not a bot — just read it back to me.
Send a $50 shipping deposit and I'll mail the item today.

These are illustrative examples written by ScamSplain, not real messages.

What the scammers want

  • A code that lets them hijack your phone number or account.
  • Deposits or payments for items that do not exist.

What to do

  • Never share a verification code with a buyer or seller.
  • Keep payments and chat inside the platform.
  • Meet in a safe public place for local deals and inspect items first.

What to do if you already responded

  • If you shared a code, secure the affected account and phone carrier login.
  • Contact your bank if you sent money.
  • Report the buyer or seller to the platform.
